About

The quadratus lumborum block (QLB) was first described by Blanco. it is a compartment block procedure during which a local anesthetic is injected into the muscle plane of the quadratus lumborum (QL) muscle under ultrasound guidance Currently, QLB is divided into four types based on the injection point of the local anesthetic: lateral, anterior, posterior, and intramuscular QLB. QLB is widely used for various types of abdominal surgeries (

Full description

the investigators will evaluate the anesthetic efficacy of quadratus lumborum block by paraspinous sagittal shift approach for hip surgery by injecting 30 ml of 0. 5% bupivacaine.

Description:

With the patient in the lateral decubitus and the block side independent, a curvilinear ultrasound transducer (2-5 MHz) will be directed caudally in a sagittal plane 3-4 cm lateral to the lumbar spinous process of L4, which is almost opposite to the iliac crest, producing a longitudinal scan of the lumbar paravertebral region; and thus identifying the transverse processes of L3 and L4, with PM muscle in-between and erector spinae muscle posteriorly. The probe is shifted slowly to the lateral side until the transverse processes disappear and the QL muscle is evident in its long axis attached caudally to the iliac crest with a characteristic sonographic image of three muscle layers appearing from posterior to anterior as: erector spinae, QL, and PM muscles respectively.
